Rolf freehub slipping(9 posts)

Well..

I have Rolf vector Comps, less than 5000 miles. Bought them in April this year. The freehub is slipping, or at least not catching the pauls when I pedal, and of course the pedal lurches forward until the pauls engage. Supergo is having trouble getting warranty info or warranty replacement from Rolf or whoever they are now. Anyone know what I can do about warranty, or is this not too hard to fix by myself?

...is that you will have to buy a Shimano freehub and have it installed. It's not horribly expensive. The bearings went out on my Comp freehub and I think the Shimano replacement was $35.00 installed.

You might just pop off the freehub to see if some junk isn't fouling up the pawls, or the spring isn't providing sufficient pressure on the back of the disk....
Is that what it looks like??Andy M-S

I've never seen the innards of a Rolf hub before, but is that what it looks like?? I'm used to thinking of the pawls as independently-moving mechanical items. It looks like (correct me if I'm wrong) the outer face of the inner disk is pushed out against the inner face of the freehub by that spring, and (since the faces are designed to engage securely only in one direction) when you stop peddling, the slipping force is great enough to overcome the spring force trying to engage the faces and--voila--tick-tick-tick.

It's not a bad idea, since it would significantly reduce the number of moving parts, but the tension in that spring would be absolutely critical and (unlike in the Shimano and Campy designs, as I understand it, where there are multiple pawls) there's no secondary backup...

Do I understand this thing correctly, or am I completely misunderstanding how the Rolf hub works?

Your assessment of the hub's functioning is correct. Not all of the Rolf hubs (Hugi) work the same (Sestrieres are quite different), but the graphic is of a first run Vector Pro (note the polished shell) that is now nearly five years old and hasn't hiccupped once... and apparently is one of a few that hasn't had problems. Indeed, the original grease was entirely too thick....

Dave,
I have a pair of Vector Pros and this has happened to me too. The problem, at least in my case, was that the shop had used grease that was too heavy for the fine teeth of the pawls. Tear em' out, clean them really well, and then re-grease with a lighter grease. This should fix the problem.

Hope this helps.

Phil Woods tenacious oil. Recommended by Trek technicians. Stopped all noise and slipping in my Vector Pros.

Those wheels were almost certainly made by Trek. If you need warranty service, I would try to contact Trek.
